Hi Stephen,
you mentioned off-line the other day about a simple switched mode PSU. Can you link in the chip and circuit diagram that your using?
Thanks.
Switched PSU
Re: Switched PSU
Its a dual voltage Lipo BuckBoost DCDC regulator with charger and battery management for a retrofit to the Rallylog I did a couple if years back for the bike club as the 9v battery and LDO regulators doesn't really cut the mustard over a two day event.
3.3v is LTC3531 buckboost regulator
5V is MCP1640 boost regulator
circuit attached, still doing the PCB side of things.

Re: Switched PSU
What are you using for drawing your schematic? Looks almost KiCAD, but cant really tell it from Eagle?
